Full breakdown
Government & politics
Australia
Australia combines a Westminster parliamentary system with a US-style elected Senate and a written federal constitution. The monarch is head of state, represented by the Governor-General, but power rests with the Prime Minister and Cabinet, drawn from the elected House of Representatives. Unusually, the Senate is powerful and fully elected, and the High Court can strike down laws that breach the constitution. Voting is compulsory.
United States
The United States has a presidential system with a strict separation of powers between three co-equal branches. The President is uniquely both head of state and head of government, elected separately from the legislature via the Electoral College. Congress writes the laws and controls spending; the President executes them and can veto legislation; the Supreme Court interprets the constitution. This system of checks and balances means power is deliberately divided — the President cannot dissolve Congress, and Congress can impeach the President.
